Given a water table model, young scholars will observe and record as pollution infiltrates the ground and surface water.

After creating a model, students will investigate factors that affect water runoff both positively and negatively, and the impact this has on the quality of groundwater.

Students design and build model landfills using materials similar to those used by engineers for full-scale landfills. Their completed small-size landfills are "rained" on and subjected to other erosion processes. The goal is to create...
